Customers say
Customers find the transformer works well with Ring doorbells and SimpliSafe cameras, and appreciate its ease of installation and good price. The power source receives positive feedback, with one customer noting it provides 28V even under load, and another mentioning it can power multiple doorbell cameras. However, the quality and lifespan receive mixed reviews – while some consider it a good transformer, others report receiving defective units, and many mention units failing within a week or three years. The heat transfer performance is also mixed, with customers noting that the transformer itself runs warmer than expected.
